USB 2.0 Video Adaptor with Audio

• bulky USB stick with LED and cables

• inputs

  • S-video (black DIN socket), untested

  • composite video (yellow RCA socket), works with SCART-to-composite cable from VCR

  • stereo audio (red and white RCA sockets), integrated audio interface is noisy and suffers from xruns, so I use my Edirol UA-25 instead

  • provided USB extension cable makes it stop working properly, plugged directly into port of powered USB hub works fine

• video formats

  • 720x576i50 PAL (bottom field first)

  • 720x480i60 NTSC (advertised, untested)

• bundled software CD for Windows 2000, Windows XP, Windows 7, Windows Vista, requiring at least Pentium III 800 with 4GB HDD and 256MB RAM.

• works fine on Debian Linux with built in usbtv driver, gives /dev/video0 or similar

  • configure with mplayer

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video0:input=0:fps=25:buffersize=256:alsa:amode=1:forcechan=2:audiorate=48000:adevice=default:forceaudio:immediatemode=0 -mc 0 -ao alsa:device=hw=4,0

• check with ffplay

ffplay /dev/video0 -vf bwdif=parity=bff

• record with ffmpeg (use meterbridge to check audio level, use qpwgraph to connect ffmpeg to correct soundcard)

ffmpeg -f alsa -thread_queue_size 64 -ac 2 -ar 48000 -i default -f video4linux2 -thread_queue_size 64 -i /dev/video0 -vf bwdif=parity=bff -pix_fmt yuv420p -profile:v high -level:v 4.1 -crf:v 16 -bf:v 2 -g:v 15 -codec:a copy "$(date --iso=s | tr ':' '-').mkv"
